Appeal No. 2002-0404
Application No. 08/859,143
(claims 7-10); and (iv) at least ten thousand pounds (avoir) of
a butyl acrylate product (claims 11-17). Further details of
this appealed subject matter are recited in representative
claims 1, 6, 7, and 11, the only independent claims on appeal,
reproduced below:
1. A process for refining a butyl acrylate-
containing stream comprising butyl acrylate, dibutyl
ether, butyl acetate, heavies and butanol, the process
comprising the steps of:
a. introducing said stream into a splitter
distillation column to provide an overhead fraction
comprising dibutyl ether, butyl acetate, butyl
acrylate and butanol and a bottoms fraction comprising
butyl acrylate and heavies;
b. withdrawing from the splitter distillation
column the bottoms fraction; and
c. separating heavies from said bottom fraction
by introducing the bottoms fraction into a butyl
acrylate distillation column to provide an overhead
product containing butyl acrylate and a bottom product
containing heavies.
6. A process for refining an acrylate containing
stream comprising ether, acetate, heavies and alcohol,
the process comprising the steps of:
a. introducing said stream into a splitter
distillation column to provide an overhead fraction
comprising ether, acetate, acrylate and alcohol and a
bottoms fraction comprising acrylate and heavies;
b. withdrawing from the splitter distillation
column the bottoms fraction; and
c. separating heavies from said bottom fraction
by introducing the bottoms fraction into an acrylate
distillation column to provide an overhead product
containing acrylate and a bottom product containing
heavies.
7. A process for the production of butyl
acrylate, comprising the steps of:
a. reacting in at least one reaction zone an
